Fix pagination

 - The error is that the Parsers is stateles.

 Between iterations the library is recreated, the only variables that
 are preserve are $state->total y $state->pointer

 The state between iterator is preserve by putting the result of fseek
 in the variable state->pointer and setting the parser with it in the
 next iteration...

 big wooooow for me... no more groping, no more shooting in the dark
Fix the chunk size of the parser to 1000 (ugly alambred)
